Abstract: | Bacterial biomass (BB, acridine orange) and bacterial secondaryproduction (BSP, [3H]thymidine incubations) were measured forthe first time in Concepción Bay (37°35'S, 73°01'W).BB ranged from 1.8x106 to 22.5x106 cells ml1 (the lattervalue observed near to an industrial effluent), BSP from 0.27x106to 2.5x106 cell ml1 day1 and heterotrophic turnoverrates between 0.15 and 1.0 doublings day1. |
